PostgreSQL 9.3
Determine if Autovacuum is Running
This is specific to Postgres 9.3 on UNIX. For Windows, see this question.
Query Postgres System Table
SELECT
schemaname, relname,
last_vacuum, last_autovacuum,
vacuum_count, autovacuum_count -- not available on 9.0 and earlier
FROM pg_stat_user_tables;
Grep System Process Status
$ ps -axww | grep autovacuum
24352 ?? Ss 1:05.33 postgres: autovacuum launcher process (postgres)
Grep Postgres Log
# grep autovacuum /var/log/postgresql
LOG: autovacuum launcher started
LOG: autovacuum launcher shutting down
If you want to know more about the autovacuum activity, set log_min_messages
to DEBUG1..DEBUG5
. The SQL command VACUUM VERBOSE
will output information at log level INFO
.
Regarding the Autovacuum Daemon, the Posgres docs state:
In the default configuration, autovacuuming is enabled and the related configuration parameters are appropriately set.
